CAN-DOUBLE-SEAMING MACHINE.

Application fil-ed J'une 9,

This invention relates to seaming machines, and more particularly to candouble-seeming machines.

In the canning industry, particularly in canning of perishable foodproducts, such as fresh i'ruit, vegetables, fish, etc., it is essentialto seal the cans as soon as possible after the product is processed andpacked. In some instances, a few hours delay in sealing the cans causesthe spoilage and total loss of 2U of the can, requiring additionaloperations i to clean the can after closing.

There are two types of closing machines in general use, the intermittentmotion feed, and continuous motion feed machines. In the intermittentmotion feed machines, the cans are fed closely spaced into the machineand the necessary time for seaming 1s provided by the dwell of the feed.This type machine is of very lov;7 capacity, as it is impossible tooperate it at high speed without spilling.

In the continuous feed closing machine, the cans are gradually separatedto a .considerable distance, this wide can spacing being necessary toaccommodate the location of seaming heads, as on this type ofclosingmachine, the seaming heads are located in a circle that revolves,as an integral part of the can feeding mechanism. This type 'of inachineis superior to the intermittent motion machine, but it has itslimitations due to the necessity of wide can s acing. In spacing cansfilled with liquid, it 1s very diiicult to accelerate the can velocitywithout spilling, as even a slight jerk is suilicient touagitate theliquid and cause it to flow over. On present machines, the cans aregenerally delivered to the seamin station by means of prongs or turretssimp y by dragging the can on a sta.- tionary support. The frictionbetween the moving can and stationary support `vibrates the can, causingagitation of the liquid and consequently the spill.

.is the most important mechanism, and it must always function perfectlyas the least defect due to wear or accident, ties up the entire canniiig operation. This is particularly true with present machines inuse, as the construction is such that it is impossible to eliminate oneor more seaming stations and continue the operation of the machine.Therefore, every caiiner whose output is limited to the capacity of onemachine is obliged to carry another machine in reserve for emergency.

My invention yrelates in general to multistation double-seaming machinesand, while trom certain aspects has more particular application todouble-scanning the lled cans, it will be manifest as the invention isbetter understood that from other aspects it has valuable uses in thecan factory for seaniing of the can bottoms as well.. v

A principal object of my invention is the provision of -a whollyautomatic, highly ef- 75 ticient double-seeming machine for circularcans, and of new and improved construction.

Another highly important object of my nvention is the provision of anapparatus of this character which will insure the continued operation ofthe machine when one or more seeming stations become disabled.

Another important object of the invention is to provide a novelelectro-magnetic can spacing and can retaining means while the cans arebeing carried to seaming stations.

Another object of the invention is the provision of a machine of thekind which, by changing of a small number of parts, may be adapted forthe seaming of cans of varying 9o height and diameter. Y

In the accompan g drawings, I Ahave shown several embodiiiiientsof theinvention. In this showing: l

Figure 13 is a vertical sectional view in substantially the same planeas Figure 1, showing part of the mechanism on an enlarged scale, and, v

Figures 14, 15, and 16 are sectional details indicating the operation ofthe seaming rolls in forming the double seam.

Referring to Figure 2 of the drawings, there is provided a number ofseaming stations 1, 2, and 3, arranged concentric to the center of themachine and so positioned with respect to a revolving turret 4 that eachseaming station makes one complete revolution to a quarter turn of theturret. The seaming stations are provided with pockets, 5, 6, and 7 of aproper size to receive the can and the turret is provided with a numberof pockets 8.'

In this instance, twelve pockets are provided on the turret. As theseaming stations make a complete revolution to each quarter revolutionof the turret, the pockets 5, v6, and 7 are alined with every fourthpocket of the turret. Cans 9 are arranged in the pocketsof the turret,and are adapted to be received. in the pockets 5, 6, and 7. Covers 10are brought into vertical alinement with the can by means to bedescribed. As shown, the can and cover are spaced a considerabledistance fromeach other (see Figure 1), when the can first enters theseaming station. A pressing pad 11 is arranged above the cover, and arod 12 is secured to this pad. This rod engages astationary cam 13 (seeFigures 1 and 13) to assemble a can and cover, as indicated in F igure 4of the drawings. After this action has taken place, the can and coverare adapted tlo be lifted by a lifting member 14 arranged beneath theseaming station. A tubular lever 15 is connected to the lifting memberand a lever 16 (see Figure 12) is pivotallymounted on a suitable support17 and is provided with a forked end 18 having pins 19 engaging theopposite sides of the lever. A cam 20 is provided with a roove 21adapted to receive a vroller 22, carried by the pivoted lever 16 toraise the lifting member and the can. This raises the can and cover intoa position immediately below a sealing chuck 23. A hollow shaft 24 isarranged within the tubular l lever 15h and this shaft is provided witha pin- `ion 25. keyed thereto. ranged within the hollow shaft and keyedAA spindle 26 is arthereto. The seaming station continuously .upperportion of the seaming station is driven through a pinion 28 from acentral gear 29. After the can has been raised to a position immediatelybelow the chuck 23, the seaming operation is performed. The performanceof the se'aming operation takes place during the greater part of therevolution of the seaming station on its axis. When the lifter startsdownwardly with a finished can, the can is ejected by a revolvingejector arm 30, (see Figure 2) and the station is ready to repeat theoperation on the next can.

The cans are delivered from a suitable conveyor (not shown) to arotating disk 31 (see Figures 1 and 2) in unrestricted position asregards spacing from can to can. It is, therefore, necessary to spaceand accelerate the can velocity before delivering the cans to the turret4. A selecting disk 32 is arranged between the disk 31 and the turret.-A plurality of electromagnets 33 equal in number to the number ofpockets on the turret, are arranged around the periphery of theselecting disk. Vanes 34 are arranged beneath the disk substantially inhorizontal alinement with the feeding disk 31 (see Figure 1 Theselecting mechanism is driven at t e same speed as the turret. Each ofthe vanes 34 is provided with a lug 35, adapted to engage the edge ofthe can. The vanes 34 are pivotally mounted on a turn-table 36. Asshown, the turn-table is provided with bearings 37 adapted to receivepins 38 carried by the vanes. An arm 39 is secured to each of these pinsand these arms ride in a cam groove formed in' a stationary disk 40. Theselecting disk 32 is eccentrically mounted and is driven through asliding coupling 41.

As shown in Figure 2 of the drawings, the I feeding disk 31 deliversthe. cans to the osition indicated by the reference numera s 42 and 43,and the cans are then attracted by the magnets 33 of the selecting disk32 and follow the path of this disk. If the can is delivered too late tobe attracted by the magnet, it remains on the feeding disk 31, asindicated at 44, and returns to the delivery point merging with theincoming cans to repeat its travel toward the selectin disk. To avoidany jamming of the cans, t e machine is operated at a slightly greaterspeed than -the conveyor or lling machine, providing ample space forunselected cans to merge into the lines of cans being fed. The lugs 35on "i cans from the magnets to rmit them to be delivered to the turret.his arrangement permits a continuous current to be maintained in themagnets. As the can is advanced by the vane 34, due to the cam 40, thecan velocity in a radial path is accelerated to the same as the turretso that when the can is, transferred to the turret at the position 46,its velocity is the same as the turret speed, eliminating possibility ofspill during the transfer. Each turret pocket is provided with avdepending arm 47 and a lower horizontal arm 48, forming a can support'.Electro-magnets 49 are arranged adjacent the can supports to maintainthe cans inthe pockets. Particular attention is called to the fact thatfrom the time the can is delivered to the feeding disk 31, it is carriedWithout any sliding or dragging motion, eliminating the possibility ofspi ing the contents and insuring a smooth action.

llurrent is delivered to the magnets on the turret by lead Wires 50 and51, connected to suitable terminals 52. The magnets 33 are supplied withcurrent through leads 54, connected to terminals on the selecting disk.The magnets 33eme connected in parallel and each magnet is provided witha suitable control switch (not shown).

s stated above, each seeming stationregisters with every fourth pocketon the turret. Pls the selecting disk is provided-with the same numberof magnets as the number of pockets in the turret, the delivery of cansto any seeming station may be discontinued by 67 and 68`are arranged atthe `bottom of the l magazine andare adapted'to'se aratethe bottom coverfrom the remain er of the Y stack of covers in the magazine.- The detailconstruction of ,these knives is shown in Figure 8 of the drawings. Asshown, the knives are carried at the ends of, a substantiallysemi-circular yoke 69, having an arm arranged betweenthe knives, andtheend of this arm is provided withva sleeve 71. Adjacent each of thepockets 65, the turrent is rovided with a lug 7 2 adapted to engage theottoni cover as it 1s separated from the stack by one of the knivesafndcarry it towardthe When the turret 62 and turret 4 register at thepointl indicated by the numeral in Figure @of the drawings, the cover ispicked up by the electro-magnets in the pockets of e turret 4 andcarried forward with the the-proper seeming station. r

`During the penod that the cover is stationary in the markingstation,that is, after the lug 72 passes over the cover and until disconnectingevery fourth magnetic unit of *the pocket 65 comes inpositionto receivethe the selecting disk, corresponding to the particular station. Theimportance of this feature will be apparent when it is considered thatany of the seaming stations may be put ont oi operation for repair orsimilar purposes and the remainder of themachine emplayed in its normalmanner. The generator may be run by the machine to furnish the currentto energize the ma ets 33 and 49. As shown, the machineis rivenfrom anysuitable source of power by means of a pulley 56 and a. gear 57 may bemounted on the -pul-l f ley hub. The generator '(not shown)' is providedwith a shaft 58, having a'gear'59 meshl spring arel connected to theshaft and tothe ing with the pinion 57 on the' pulley. By

stack of covers rests on a support 92 on the4 opposite side of themagazine and the knife 67. A similar support 93 is arranged on the'opposite side of the magazine to cooperate with the knife 68. The pawl89 which locks the shaft 86 is controlled by a solenoid 94, and a triplever 20', Figure 2. This trip lever is provided with suitable contactpoints so that when a passing can comes .in contact with the lever, acircuit is closed and solenoid 94 depresses the pawl 89 through aplunger 95, releasing the cover separating mechanism to cut off onecover, which is finally delivered at the point 75 in Figure 2 of thedrawingsf by a pair of eccentrics 97 and 98, mounted on a shaft 99. Thisshaft is provided with a bevel gear 100, meshing with a bevel gear 101to drive the marker. The upper jaw 76 is reciprocated and the lower jaw77 is made in the form of a plunger and is also reciprocated.

The eccentric 98 is provided with a strap 102,

the upper end of which is connected to a threaded rod 103. This rod isreceived within a tubular member 104 and the tubular .'member isprovided with a pin 105, adapted tween the nut and the head 107. Thelower end of the jaw 77 is provided with a slot 109, adapted to receivea portion 110 of the head 107. The head is secured to the jaw by a pin111. The jaw 76 is mounted on a substantially U-shaped member 112,provided with a depending portion 113, which receives the lower jaw andthe lower jaw operating mechanism. This depending portion is connectedto a strap 114 carried by the eccentric 97 by arms (not shown). Anadjustable stop 115 is arrangedV within the depending member 113. Thismember is provided for the purpose of controlling the depth of thelmpression in the cover and also acts as a safety means to avoid scoringthe cover when the dies are of uneven depth. It is ada ted to beadjusted so that on the upstrokeof t e plunger 77, it is engaged by anabutment 116,

, formed on the lower end of the plunger. This stops the movement of theplunger and the excessive stroke of the eccentric 98 is taken up by thespring 109.

Referring to Figures 1 and13 of the drawings, the seaming station isprovided with a head-frame 117, which is supported in suitablelbea-rings 118 and-119. This frame revolves on the axis of the shaft 26and carries the entire seaming mechanism. When a can is delivered to theseaming station, the can and cover are assembled as shown in Figure 4 ofthe drawings, and are brought in contact with the chuck 23. The seamlngoperation extends through the greater part of the revolution of theseaming station on its axis.

Referring to Figures 14, 15 and 16 of the drawings, the seaming is aspinning operation performed in a gradual way to Yinsure a smooth andtight joint lbetween the can and the cover. The seaming operation isperformed in two steps.. With the can and cover -in position beneath thechuck, as shown in Figure 14 of the drawings, seaming rolls 119 locatedon diametrically. opposite sides advance toward the can, curling thecover as indicated at 120 in Figure 15 of the drawings. After thecurling or rst operation, another pair of rolls 121 are brought incontact with the curled edge of the cover and the flange of the can andthe curled seam is flattened out to produce the double seam 122 shown inFigure' 16 of the drawings. At the completion of this operation, thelifter or can support 14 starts on the downward stroke and the-can iscarried away by the arm 30.

The chuck is supported on a chuck spindle 123 rigidly mounted in theheadI frame 117. The chuck is arranged within a seam.- ing head 124 andthis head and a sleeve 125 are revolved on the vertical axis of thechuck spindle through gears 126 and 127, carried by the head and thesleeve respectively (see Figures 1 and 13). The head gear 126 is drivenby an internal gear 128 so proportioned that when the seaming stationcompletes a rev'oluf tion on its axis, the head gear completes tenrevolutions. The sleeve 125 in the meantime completes elevenrevolutions. The gear 127 meshes with an internal gear 129 arrangedabove the internal gear 128.

Referring to Figure 4 of the drawings, the

seaming sleeve 125 is provided with eccentrics 130 and 131 located ondiametrically opposite sides. Each eccentric operates an adjacent pairof seaming rolls through links 132, 133, 134, and 135, diagrammaticallyillustrated in Figure 6 of the drawings. The reciprocating movement isimparted to the seaming rolls, due to the dilerential speed between theseaming head 124 and the seaming sleeve 125, as previously described,their respective speeds being ten and eleven revolutions. A similarresult may be obtained at any other speed as long as there is adifference in speed between the seaming head tract before 137,representing the second.y

eration roll, is brought in contact with tige can. The rolls-119 aremounted on spindles 138 and these spindles are provided with adinstablemeans consisting of eccentric sleeves 139 and 140.`

`of diiferent diameters.

Referring to Figure 5 ofthe drawings, it will be noted that when sleeves139 and 140 are turned in opposite directions, the spindle 138 willadvance in a straight line as indicated. This permits adjustment of theseaming roll 119 toward and away from the axis of the seaming station,permitting the use of the apparatus with cans of varying diameterswithout displacing the seaming roll from its fixed radial location whichis very important on account of head timing.

The outer eccentric sleeve 139 is supported in rocking arms 141and '142.These arms are pivoted lon a bearing 143 and may be adjusted `by meansof a worm 144 (see Figure 7). The

eccentric sleeves 139 and 14() are provided lwith suitable markings ontheir upper ends, as indicated at 147 and 148 to facilitate quickscttiinlr of the roll 119 to accommodate cans The arm'145 is connectedto a link 149 by a pin 150, and this link is pivotally mounted on a stud151 extending through the bearing 143.

.After ltheseeming rolls have been set, the arm and the link 149 willoccupy the po sition 152 in Figure 7 of the drawin s. By swinging thearm and link to the position 153, the seeming roll is thrown outofengagement with the can dueto the eccentricity of the sleeve 140. Thispermits any roll to be disengaged from the can and rendered inoperativewithout losing the correctrsetting posi tions, for example, three rollsmay be disengaged to examine the function of the fourth roll and bysimply resetting each arm and link, 'the entire mechanism is again inproper alinement. The stud 151 extends through a sleeve 154. A spring155 is arranged withinthe sleeve to normally force the stud upwardly.The lower end ofthe stud is provided with a handle 156 bv means of whichit may be moved downwardly against the tension of the spring 155 torelease the link 149.

The connecting links 134 of the second op eration rolls 121 are providedAwith springs 157, as shown-1in Figure 7 of the drawings. These springsareamounted on bolts 158 and retained in position by nuts 159. Incompleting the second operation, it isv necessary to exert considerablepressure on the can and cover to insure atight joint, but diie tov thevariations in commercial tin and also tothe additional,thickness?onYtheA side seam of thel can body, it `is almost impossible to make ,aerfectseam Without some cushioning means.

tops 160 are placed between the seeming rolls and these stops serve toprevent curling oV f of the can over the chuck if, for any reason,

a can is delivered to the seeming station with, out a cover. Theapparatus is provided with a housing 161 and this housing and theseaming mechanism are supported on a stationary column 162. This housingma Ibe adjusted by means of a screw 163 to any esired height. A pinion164 is slidably mounted on the main shaft 165 and this pinion transmitspower to an intermediate gear 166 freely mounted on a sleeve 167. Thegears 164 and 166 are connected/through a train of gears 168, 169 and170, as shown. The gear-166 meshes with an internal gear 171 to operatethe seaming heads, as previousl described. A pinion 17 2 is arranged ont e lower end of the main shaft 165 and this pinion drives the lower vmechanism of the machine through a gear 173, gear 174, and gear 175,which is loosely mounted on the column, and drives gear 176.

The gear 176 is mounted on an intermediate shaft 177, which carries thebevel gear 101, and this shaft operates the gear 27 through a pinion178. The turret is carried by a sleeve 179, and the turret and' gear 29,which are slidably connected to the gear 27, revolve on the stat1onarycolumn 162. It will be noted that gears 27 and 25 are identical to gears29 and 28 and both'trains revolve as a single unit, operating the4seaming station on the axis' of the shaft 26. The lifter cam 20 iscarried by the gear 175 and revolves at the same speed as the seemingstation.

The intermediate shaft 177 is provided wlth a worm 180 which drives thehorizontal shaft 181 through a worm gear 182. The in through gears V19()and 191. A clutch con-` trol lever 192 is adapted' to connect a Wormwheel 193y to lthe gear 169. This permits manual operation of themachine by means of a worm 194, meshing-with the worm wheel 193andmounted on a shaft 195. The shaft 195 may be provided with a suitablehand wheel (not shown) to permit manual operation of the machine throughthe worm.

The pulley clutch is of a friction disk type, as shown in Figure 1 ofthe drawings. A spring 196 engages the pulley 56 and connects 1tto adrlving plate 197, throu hiloating disks 198. This provides a sa. eclutch action with gradual pick-up, and even if the Y idly, the floatingfriction isks will engage 6 v yLeeaoee the driving plate graduallyeliminating grabbing action and. damage to the machine.

In Figure 3 ofthe drawings, I have shown a modified form of theinvention in which the cans designated by the reference numeral 199 arecarried in pockets on an endless conveyor (not shown) and the seamingstations 200 are arranged beside the conveyor functioning in the samemanner as the tangentially arranged seaming stations shown in Figure 2of the drawings.

In operation, the cans are delivered to the turret 4 by the feedingdiskl and the sel lecting mechanism. As previously described, the cansmay be fed to the feeding disk without spacing them and the selectinmechanism delivers the cans in proper or er to the pockets 8 of theturret. The seaming stations 1, 2, and 3 receive the cans from theturret in the pockets 5, 6, and 7. The seam ing stations make a completerevolution to each quarter revolution of the turret and -when the turretis provided with twelve pockets, as shown, each seaming stat-ionreceives the cans from every third pocket of the turret. I one of theseaming stations is out of order, the magnets of the selecting mechanismcorresponding thereto may be disconnected and the machine operated withthe seaming station out of service. This is important as it -permits anyseaming sta-.

tion to be repaired without interfering with the opera-tion ofA the restof the machine.

Eachseaming station continuously revolves on its own axls, being drivenby the gears `27 and 29 through the pinions 25 and 28.

The cam 2O raises the lower half of the seaming station, after the coverhas been placedv in position and the seaming operation is performed bythe rolls 119 and 121.' Particular attention is called to the adjustingmeans which permits the rolls to be adjusted radially of thev seamingstation for use with cans of diierent diameters.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to without departing from the's irit of the invention or thescope ofthe subjoined claims.
